Abstract
Containment sacs insertable into a body cavity through a minimal access incision for purposes of containing, manipulating, treating and/or extracting material from the body cavity. The sac may comprise a flexible sac body having at least one opening thereinto and a resilient or spring loaded rim member disposed about the opening to urge the opening to an open configuration when deployed in the body cavity. The containment sac may be further utilized in combination with a dedicated introducer sheath through which the containment sac may be inserted and extracted. A valving member may be positioned on the introducer sheath to prevent escape of gas from a pressurized body cavity such as a pneumoperitoneal. The containment sac may incorporate a grasping member whereby the containment sac may be grasped and inserted using a standard forecep/grasper instrument. Alternatively, the containment sac may be attached to an elongate rod member usable to insert and extract the containment sac. Additionally disclosed is an expandable embodiment of the containment sac which may be selectively expanded through the use of a separate expansion instrument or balloon.
